Nowadays, in the times of the increased production and consumption, the cars are not just the means of transport, but also a status symbol. Cities are forced, due tothe intensive development of their transport strategy, to achieve the well-being of their environment. The impossibility of expanding the capacity of the central city for the majority of European - and particularly cities in transition countries such as Croatia, an unpopular solution of congestion charging, soon would become the only possible. The Congestion charge is so far decided only within a few cities, but is also proved to be very successful.
City centers are not built to proceed modern traffic, such "converting" brings unavoidably many problems, such as traffic jams. In short, traffic congestion is a condition characterized by reduced flow, longer travel times and increased nervousness and pollution,
which leads participants of traffic to direct or indirect threat. One of the measures that can be successfully impacted on reducing congestion and thus its negative consequences - such as increased external costs and the administration fee of congestion, are the models fees that drivers pay to enter the city center. This was successfully conducted in cities such as London and Stockholm, but the main challenge in the implementation of it worldwide is the public resistance. In Croatia, this strategy, despite the conducted studies, because of the ever-present crisis, is still not implemented.
